TMUX6119: Leakage Current Specs on the Datasheet

Jerry Molnar
Prodigy 210 points
Part Number: TMUX6119

Hi!
I guess this is a 2 part question -

[1] On the front page of the datasheet - the highlights in the bullet point list - it says "Low Leakage Current 0.5pA".

I assume that this is a typo and the info in the parametric tables is correct...The table states the typical (25C, +15V/-15V rails) leakage as .005nA or... 5pA

Can you confirm that the typical leakage is 5pA?

[2] I'd like more insight into the leakage current specs please.
In our application, we'll be biasing the device at +5V, -5V. Our operating ambient temp is 15C-30C.
The signals we'll be switching will be centred around 1.5V with a maximum differential voltage across the switch of 600mV.

Does the lower voltage across the switch vs what is shown in the datasheet translate to a lower typical and lower min/max values of leakage?

Is there any characterization data that you can share that shows the variation of leakage current with temperature?

Thanks!
Jerry

    Hello Jerry,

    We will take a look at this an get back with you thanks!

    Hello Jerry,

    1. Your are correct in the fact that the actual leakage current is 5pa we are currently working to fix this in the datasheet!

    2. In addition because leakage current is temperature dependent there should not be any significant change to it based on voltage.

    Also i know this these graphs  of leakage vs temperature are on the datasheet but they show some of the information you might need.

     

    I am not sure if we have characterization data at your specific application but please let me know if you need any further information!

    Regards,

    Kameron

    Hi Kameron,

    Thanks for your reply. 


    The graphs don't have enough resolution at our temperatures to answer the question.
    Ideally, we would like to see the 5-35C leakage data on a Y-axis scale of something like -25pA to 25pA...and not single data points but more data points to get an idea of the spread across a number of parts when the leakage is measured at a given temperature. 


    Another way to possibly look at is a graph or Excel sheet that shows the average leakage data at given temperature points along with the standard deviation and median of the data collected from a number of parts at that temperature point.

    Basically looking for more insight into the leakage data!  

    Thanks and Best Regards!

    OK understood!

    Please allow me sometime to find this data( if we have it ) and send it over to you

    Thanks
